Background

The pulse generator is the most important execution unit in the measurement while drilling system. Shear valve type mud pulsers are the most reliable mud pulsers recognized in the field of oil drilling. The pulse generator utilizes a circuit to control a motor to drive a rotor to carry out reciprocating shearing motion, and a slurry channel is closed/opened through the rotation of the rotor so as to generate slurry pressure pulse. The shearing valve type slurry pulse generator can shear the plugging agent materials blocking other pulsers, so that the working condition of adding the plugging agent can be adapted.

In the field usage, particles such as sand in the slurry can be accumulated between the excircle of the shear valve type slurry pulse generator valve group and the inner hole of the hanging nipple, and can be more and more dried, so that the friction force between the excircle of the valve group and the inner hole of the hanging nipple can be very large, the conventional method is not easy to take out the shear valve type slurry pulse generator from the hanging nipple, and therefore the instrument cannot be replaced and maintained.
